how about the cummulative effect of xrays to people as we know they accumulate in the body? no?
how about the tsa smucks that operate the open machines all day long and how about the airplane crews - stewardess and all...
i guess Michael Chertoff who is the sole adviser to the manufacturer is laughing is ass off by fooling everyone and raking in advising fees...he was the one approving/recommending these machines as head of TSA - criminal intent...tell it to all the unhappy people being subject to xrays everyday.
